I met the same issue, the difference is while i touch the track pad or move mouse or hit keyboard, the screen responds rapidly and then back to black. tap the keyboard, it beeps... I can do nothing except "command+control+power" to restart or long press power to power off it.
I found it only happens after I installed 10.8.2, it works well before 10.8.2 update.
any help please?

SMC reset will fix it, but only for a few sleep cycles, then you'll need to do a SMC reset again.
1. full power down via shut down
2. control-option-shift power (when the computer is off)
3. regular power on.
things should work for a bit... then will have the same problem, repeat the steps every few days, and you'll have no problems...

I believe, i've found the solution to my problem. I read somewhere, that if you put your mac in sleep mode by accessing the apple menu, instead of just closing the lid you won't have the problem. So far it has been working perfectly, and i haven't experienced any of my previous problems.
